Compressed Hydrogen Storage Tank Design
Customer requirement list :
1. Storage tank volume is approximately 1 liter.
2. Hydrogen is compressed to 8 bar of gauge pressure.
3. Normal operating condition (room temperature and humidity).
4. Output and input port for hydrogen filling and exerting.
5. Add pressure regulator for output port.
6. Maximum budget is 500.000 rupiah.
Determining hydrogen phase :
According to hydrogen phase diagram above, hydrogen at 8 bar of gauge pressure and 25 degree Celsius, is in gaseous phase.
Determining tank size :
First step is to determine the tank inner diameter : 100 mm
According to the equation above, the inner height of the tank is h = 1.000.000 / 3,14 x 50 x 50 = 127,32 mm
Tank design calculation :
All of the design calculation are based on ASME Section VIII Pressure Vessel standardization.
1. Material allowable stress value :
Material : ASTM A36 sheet metal ; Yield Strength (Sy) : 36 Ksi
Allowable stress value = 2/3 x Sy = 24 Ksi
2. Wall and head minimum thickness :
Thickness formula for circumferential stress direction :
